Ebhodini Diagnostic

I-OBD sisishunqulelo se-On-Board Diagnostic ngesiNgesi, kwaye inguqulelo yesiTshayina yi "On-Board Diagnostic System" .Le nkqubo ibeka iliso kwimo yokusebenza ye-injini kunye nesimo sokusebenza kwenkqubo yokukhupha igesi emva kokunyanga nanini na, kwaye iya kukhupha isilumkiso ngokukhawuleza ukuba nayiphi na imeko enokubangela ukukhutshwa okugqithisileyo kufunyenwe.Xa inkqubo idiliza, ukukhanya okungasebenzi (MIL) okanye injini yokukhangela (Khangela i-Engine) ukukhanya kwesilumkiso kuvuliwe, kwaye inkqubo ye-OBD iya kugcina ulwazi oluphosakeleyo kwimemori, kunye nolwazi olufanelekileyo lunokufundwa ngendlela yephutha. iikhowudi ngokusebenzisa izixhobo eziqhelekileyo zokuxilonga kunye ne-diagnostic interfaces.Ngokuhambelana nokukhawuleza kwekhowudi yephutha, abasebenzi bokulondoloza banokukhawuleza kwaye bachaze ngokuchanekileyo uhlobo kunye nendawo yephutha.

Iimpawu ze-OBDII:

1. Ubume besihlalo sokuxilonga sesithuthi esidityanisiweyo yi-16PIN.

2. Inomsebenzi wokuhanjiswa kwedatha yohlalutyo lwamanani (i-DATA LINK CONNECTOR, ebizwa ngokuba yi-DLC).

3. Dibanisa iikhowudi zeempazamo ezifanayo kunye neentsingiselo zohlobo ngalunye lwesithuthi.

4. Ngokuqhuba umsebenzi werekhodi.

5. Inomsebenzi wokuphinda ubonise ikhowudi yempazamo yememori.

6. Inomsebenzi wokucoca ikhowudi yephutha ngokuthe ngqo ngesixhobo.

Izixhobo ze-OBD zibeka iliso kwiinkqubo ezininzi kunye namacandelo, kubandakanywa iinjini, i-catalytic converters, i-particulate trap, i-oxygen sensors, i-emission control systems, i-fuel systems, i-EGR, kunye nokunye.I-OBD ixhunywe kwiyunithi yokulawula i-electronic (ECU) ngolwazi lwecandelo elinxulumene nokukhutshwa. , kunye ne-ECU inomsebenzi wokufumanisa kunye nokuhlalutya iimpazamo ezinxulumene nokukhutshwa.Xa ukusilela kokukhutshwa kwenzeka, i-ECU irekhoda ulwazi lokungaphumeleli kunye neekhowudi ezinxulumeneyo, kwaye ikhupha isilumkiso ngokukhanya okungaphumeleli ukwazisa umqhubi.I-ECU iqinisekisa ukufikelela kunye nokuqhutyelwa kolwazi lwempazamo ngokusebenzisa ujongano oluqhelekileyo lwedatha.
